To all whom'fit may'cpncern:

\ Be it known that; I, JOHN BURRY, a citizen,v

of the UnitedStates, residing at'Ridgefield i Park, the county of Bergen-and'State of New Jersey,\have invented certain new-and usefuly'improvements in Selecting Devices for Electrical Signaling thefollowin is aspeciicatio'n, reference being had to t e drawingsaccompanying and forming a art of the same. -v f-Lf The subJeet4 f mypresent .applieationisa combination .of instrumentalities 'by means fvowhichthe electrical control of anumber of remote devices, such assignal bells, printing magnets or the like `may be readilypvand reliablyeffected, so that each o r any of the'same may be .operated at will inany ,dsiredordem or'at any required intervals;

Fig.,2 .is la detailed view, 'partly' in section, of .t'herjdrumand oneof t binations of portions' of the contact strips which deterrmne theselection of the appro- In the form in which my illustrated, theapparatus involves the use of a series of contact plates 1, eachcontrolling' one terminal of a circuit in which is included someelectrical device to be operated from a remote point, and which, forpurposes of illustration, I have represented as incandescent lamps 2.All of these lamp circuits run to a common generator 3, and arecompleted seriatim by the trailer 4, which is connected to .the oppositepole' of the generator 3.- This arrangement is typical of the ordinarysunlflower circuit, controller, a ty e-wheel `or a similar device, andmay be' varled within'any limits-permissible in such instruments.. 'Thedisposition differs, however, from that ordinarily used in having insome part of the circuit common to all of the circuits 2 a con#improvement is troller consisting, preferably, of a circuit n breakinarmature 5, operated lby a magnet 6 lin an in ependentcircuit.

, series of contact strips 10, 11, 12, electrically connected togetherand included in the cir- '.cuit with-magnet 6, which? contains also alocalbatteiy 13, and is in this particular in stance completed throughthe shaft 7 and If the drum have a-uniforml conducting surface, it isevident -that the circuit includrio l trailer 4, I employ the followingmeans: The

ing magnet 6 would always remain closed, which, in the particulararrangement shown, would keep the circuits of the sunilower constantlyinterrupted. To break the circuit of ma net 6, therefore, atpredetermined pe- (Is with reference to the travel of the studs or pins9 are set in the drum along lines corresponding'in an ular position tothe position of the severa contact plates of the sunower. Thearrangement of the *studs will be understood by referrin to Fig. .4. Letit be assumed that in the st line1 the studs are so placed as tointerrupt the contact between the drum and the terminals either byraising'all of the stri s off from the drum or otherwise. While t esestudsvare under the strips 10, therefore, the circuit of magnet 6 Will ebroken and the circuit completed through that plate of the sunflowerupon which the trailer rests. In all'other lines the studs are laced -sothat at least one of the strips 10, so ong as they remain in the saineposition or condition, Will be in'contact with the drum and the circuitof magnet 6 will remain closed. In order, however, that the interruptionof the relay circuit may occurat otherV predetermined oints during thetravel of the trailer, I provide for the interruption of contact betweenall of the strips and the drum by different arrangements of the studs inthe other lines and by shifting the position ofthe strips. -For example,fin line 2 the studs are so placed that strips 10 and 11 will be raisedby corresponding studs,

but the third stud has been shifted out of the normal line of strip 12so that the latter-Will not be raised unless it is turned to one side orinto the path of the displaced stud.

I have not deemed it necessary to ,'illustrate or describe the means forrotating the drum and trailer, norto Ashow the c orrespond-v ing devicesat the transmitting station, as

these :are all matters well understood in the art.

A greater number' of strips may be used and with each increase-a eaternumber of possible combinations wi l be afforded. I may call attentionto the fact that while I have shown devices for moving the strips bodilyas the 'means of providing contacts in different positions withrespectto the drum, this is not necessary, as any means that willprovide for the interruption or completion of4 i contact between theseveral branches of the circuit of batte 6, at the points indicated inthe diagram o Fig. 4, may be employed.

Having now'described my invention, what I claim is:

In an apparatusof the kind described, a selecting device comprisingin combination, a rotary drum having series of studs or projections at,lpredetermined points on its periphery a controlling circuit with aplurality of terminals bearing on the drum, and means for varying thepositions of such terminals relative to their respective series of studsor projections on the drum, whereby the said circuit may be interruptedby the studs at any oi all of the terminals in given positions of thedrum, as set forth.
